SoloPower plans to halt operations at its Portland solar panel plant on June 17, company officials alerted the state today.

The California-based startup plans to layoff 29 workers, including 10 engineers, as part of the move. It received millions in incentives to build the Portland panel plant, but its launch fell months behind its promised benchmarks.

Julian Biggs, the company's chief legal officer, said the decision came as a result of "a significant downturn in business and the need for a major reorganization."
